Chronic granulomatous disease (CGD) is an inherited autosomal recessive or X-Linked primitive immunodeficiency (PID), due to a defective nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex impairing anti-infectious and anti-inflammatory role of peripheral blood mononuclear cells. It is characterized by severe bacterial and fungal infections and by excessive inflammation leading to granulomatous complications. This work was made over a period of 34 years on 41 Tunisian patients suffering from CGD. Cumulative follow-up of patients was 2768.5 months, median 31 months. Survival was studied by survival curves according to Kaplan-Meier method. Lymphatic nodes, pulmonary and cutaneous infections predominate as revealing manifestations and as infectious events during patients' monitoring. At study end 12 patients died mainly of invasive pulmonary aspergillosis and septicemia. Median age of death was 30 months. CGD remains compatible with a decent quality of life. Early diagnosis, anti-infectious prophylaxis, and initiation of adequate management, as soon as complication is perceived, promote pretty good evolution.
